# Execute Commands Examples

The execute-commands goal allows you to execute commands, in the CLI format, on the running WildFly.

## Execute commands

The example below shows how to add a debug logger with a debug log file:

    <project>
        ...
        <build>
            ...
            <plugins>
                ...
                <plugin>
                    <groupId>org.wildfly.plugins</groupId>
                    <artifactId>wildfly-maven-plugin</artifactId>
                    <version>3.0.0.Final</version>
                    <configuration>
                        <commands>
                            <command>/subsystem=logging/file-handler=debug:add(level=DEBUG,autoflush=true,file={"relative-to"=>"jboss.server.log.dir", "path"=>"debug.log"})</command>
                            <command>/subsystem=logging/logger=org.jboss.as:add(level=DEBUG,handlers=[debug])</command>
                        </commands>
                    </configuration>
                </plugin>
                ...
            </plugins>
            ...
        </build>
    ...
    </project>

## Execute commands from CLI scripts

The example below shows how to execute commands from a CLI script:

    <project>
        ...
        <build>
            ...
            <plugins>
                ...
                <plugin>
                    <groupId>org.wildfly.plugins</groupId>
                    <artifactId>wildfly-maven-plugin</artifactId>
                    <version>3.0.0.Final</version>
                    <configuration>
                        <scripts>
                            <script>config.cli</script>
                        </scripts>
                    </configuration>
                </plugin>
                ...
            </plugins>
            ...
        </build>
    ...
    </project>

## Example of a CLI script to set the transaction timeout to 600 seconds.

    batch
    # set default transaction timeout
    /subsystem=transactions:write-attribute(name=default-timeout, value=600)
    #...
    # Execute and reload
    run-batch
    :reload

## Execute CLI commands in a new process

The example below shows how to execute commands in a forked process. This allows for CLI commands, such as module add, to be used.

    <project>
        ...
        <build>
            ...
            <plugins>
                ...
                <plugin>
                    <groupId>org.wildfly.plugins</groupId>
                    <artifactId>wildfly-maven-plugin</artifactId>
                    <version>${version.org.wildfly.plugin}</version>
                    <executions>
                    ....
                    </executions>
                    <configuration>
                        <fork>true</fork>
                        <jboss-home>${wildfly.dir}</jboss-home>
                        <command>module add --name=org.wildfly.plugin.example --dependencies=org.jboss.logging --resources=${project.build.directory}${file.separator}example.jar</command>
                    </configuration>
                </plugin>
                ...
            </plugins>
            ...
        </build>
        ...
    </project>

## Execute offline embedded CLI scripts

The example below shows how to execute commands offline from a CLI script, which is useful for running scripts that embed server or host controller.

    <project>
        ...
        <build>
            ...
            <plugins>
                ...
                <plugin>
                    <groupId>org.wildfly.plugins</groupId>
                    <artifactId>wildfly-maven-plugin</artifactId>
                    <version>${version.org.wildfly.plugin}</version>
                    <configuration>
                        <!-- Tells plugin to start in offline mode, to not try to connect to server or start it-->
                        <offline>true</offline>
                        <commands>
                            <command>/system-property=org.jboss.example.runtime:write-attribute(name=dev)</command>
                        </commands>
                        <jboss-home>${wildfly.dir}</jboss-home>
                        <!-- where to out log-->
                        <stdout>${project.build.directory}/wildfly-plugin.log</stdout>
                        <!-- java opts with which CLI is started with -->
                        <java-opts>
                            <java-opt>--add-modules=javax.se</java-opt>
                            <java-opt>-Xmx256m</java-opt>
                        </java-opts>
                        <!-- system properties that can than be referenced in CLI script-->
                        <system-properties>
                            <public.ip>${node0}</public.ip>
                        </system-properties>
                    </configuration>
                </plugin>
                ...
            </plugins>
            ...
        </build>
        ...
    </project>

## Execute offline embedded CLI scripts

The example below shows how to execute commands offline from a CLI script, which is useful for running scripts that embed server or host controller. Note that the java-opts in this example shows how to set JVM options with a space delimited set of options rather than an array.

    <project>
        ...
        <build>
            ...
            <plugins>
                ...
                <plugin>
                    <groupId>org.wildfly.plugins</groupId>
                    <artifactId>wildfly-maven-plugin</artifactId>
                    <version>${version.org.wildfly.plugin}</version>
                    <executions>
                    ....
                    </executions>
                    <configuration>
                        <!-- Tells plugin to start in offline mode, to not try to connect to server or start it-->
                        <offline>true</offline>
                        <scripts>
                            <script>scrip-name.cli</script>
                        </scripts>
                        <jboss-home>${wildfly.dir}</jboss-home>
                        <!-- where to out log-->
                        <stdout>${project.build.directory}/wildfly-plugin.log</stdout>
                        <!-- java opts with which CLI is started with -->
                        <java-opts>${modular.jdk.args}</java-opts>
                        <!-- system properties that can than be referenced in CLI script-->
                        <system-properties>
                            <public.ip>${node0}</public.ip>
                           ....
                        </system-properties>
                    </configuration>
                </plugin>
                ...
            </plugins>
            ...
        </build>
        ...
    </project>
